Computer Generation

The History of Computers

an electronic device which is capable of receiving information (data) in a particular form and of performing a sequence of operations in accordance with a predetermined but variable set of procedural instructions (program) to produce a result in the form of information or signals.

What is computer

Abacus The abacus was an early aid

for mathematical computations. Its only value is that it aids the memory of the human performing the calculation. A skilled abacus operator can work on addition and subtraction problems at the speed of a person equipped with a hand calculator (multiplication and division are slower).

Slide Rule

Napier's invention led directly to the slide rule, first built in England in 1632 and still in use in the 1960's by the NASA engineers of the Mercury, Gemini, and Apollo programs which landed men on the moon.

Blaise Pascal In 1642 Blaise Pascal, at age 19, invented the Pascaline

as an aid for his father who was a tax collector. Pascal built 50 of this gear-driven one-function calculator

Charle’s Babbage By 1822 the English

mathematician Charles Babbage was proposing a steam driven calculating machine the size of a room, which he called the Difference Engine.

Hollerith’s Inovation By using punch cards,

Hollerith created a way to store and retrieve information.

This was the first type of read and write technology

First Generation Computers The period of first generation was 1942-1954

The main features of First Generation are: Vacuum tube technology Unreliable Supported Machine language only Very costly Generate lot of heat Slow Input/Output device Huge size Need of A.C. Non portable Consumed lot of electricity

vacuum tube

Second Generation Computers The period of second generation was 1952-1964.

The main features of Second Generation are: Use of transistors Reliable as compared to First generation computers Smaller size as compared to First generation computers Generate less heat as compared to First generation computers Consumed less electricity as compared to First generation computers Faster than first generation computers Still very costly A.C. needed Support machine and assmebly languages

Second Generation Computers Second generation

computers also saw a new way data was stored

Punch cards were replaced with magnetic tapes and reel to reel machines

Examples of Punch Cards

Third Generation Computers The period of third generation was 1964-1972.

The main features of Third Generation are: IC used More reliable Smaller size Generate less heat Faster Lesser maintenance Still costly A.C needed Consumed lesser electricity Support high level language

Fourth Generation Computers The period of Fourth Generation was 1972-1990.

The main features of Fourth Generation are: VLSI technology used Very cheap Portable and reliable Use of PC's Very small size Pipeline processing No A.C. needed Concept of internet was introduced Great developments in the fields of networks Computers became easily available

The period of Fifth Generation is 1990-2004

Robotics Neural networks Game Playing Development of expert systems to make decisions in real life situations. Natural language understanding and generation. Development of true artificial intelligence Development of Natural language processing Advancement in Parallel Processing More user friendly interfaces with multimedia features Availability of very powerful and compact computers at cheaper rates

Fifth Generation Computers

Sixth Generation ComputersCloud Computing is a general term used to describe a new class of network based computing that takes place over the Internet,

basically a step on from Utility Computing a collection/group of integrated and networked

hardware, software and Internet infrastructure (called a platform).

general public, enterprises, corporations and businesses markets

Cloud Computing

Seventh Generation Computers

The period of Seventh Generation is Future .
